You can add a layer to an image by dragging an image file from Bridge, or from the desktop in
Explorer (Windows) or the Finder (Mac). You’ll add another flower to the postcard now.
1. If Photoshop fills your monitor, reduce the size of the Photoshop window:
On Windows, click the Restore button ( ) in the upper right corner, and then drag the
lower right corner of the Photoshop window to make it smaller.
On a Mac, click the green Maximize/Restore button ( ) in the upper left corner of the
image window, or drag the lower right corner of the Photoshop window to make it
smaller.
2. In Photoshop, select the Pineapple copy layer in the Layers panel to make it the active
layer.Blending modes
Blending modes affect how the color pixels on one layer blend with pixels on the layers
beneath them. The default blending mode, Normal, hides pixels beneath the top layer unless
the top layer is partially or completely transparent. Each of the other blending modes lets you
control the way the pixels in the layers interact with each other.Often, the best way to see how a blending mode affects your image is simply to try it. You
can easily experiment with different blending modes in the Layers panel, watching the image
change as you move the mouse over different options in the Blending Modes menu. As you
experiment, keep in mind how different groups of blending modes affect an image.
Generally, if you want to:Darken your image, try Darken, Multiply, Color Burn, Linear Burn, or Darker Color.
Lighten your image, try Lighten, Screen, Color Dodge, Linear Dodge, or Lighter Color.
Increase the contrast in the image, try Overlay, Soft Light, Hard Light, Vivid Light,
Linear Light, Pin Light, or Hard Mix.
Change the actual color values of the image, try Hue, Saturation, Color, or Luminosity.
Create an inversion effect, try Difference or Exclusion.The following blending modes often come in handy, and can be good places to start your
experimentation:Multiply does just what the name implies: It multiplies the color in the underlying
layers with the color in the top layer.
Lighten replaces pixels in the underlying layers with those in the top layer whenever the
pixels in the top layer are lighter.
Overlay multiplies either the colors or the inverse of the colors, depending on the
underlying layers. Patterns or colors overlay the existing pixels while preserving the
highlights and shadows of the underlying layers.
Luminosity replaces only the luminance of the underlying colors with that of the top
